Lou Derry, Earth & Atmospheric Sciences

Derry's research includes studying biogeochemical processes at multiple time scales, from modern environments to the evolution of couple biogeochemical cycles over Earth history. Recent work includes elemental speciation and cycling in soil-plant-water systems, and the role of atmospheric deposition. Longer time scale problems include work to quantify CO2 and elemental fluxes in the Himalayan and island arc systems. Derry is actively involved in developing models for the interpretation of carbon, nitrogen, sulfur and strontium isotopic variations in the ancient oceans and how those can be used to constrain critical environmental conditions during major evolutionary and/or extinction events.
